Caus i want the barcode to be red by a scanner.So it has to be digital code not numbers.Its for handicaped persons.I want them to enter a number and then it loads the graphical code which we will be scanned by others.sorry for my bad english.
While not as cheap as a typical LCD you can use an e-paper display, Adafruit sells a few graphic eInk dev boards for roughly $35 USD which are advertised as being able to produce a barcode readable by a laser scanner.
Why does the information need to be scanned?
